The Traffic Identification in IC Networks It is a necessary process in certain situations, such as during troubleshooting, for your own documentation, or during an audit…

It is in industrial settings where it takes on the greatest importance, thanks to advances in communication protocols that are being incorporated into Ethernet and TCP/IP standards to enable integration with other systems and technologies, ultimately giving rise to what is now known as the IIoT and Industry 4.0.

This integration has, of course, some risks as exposure within the network increases considerably, taking as highly advisable to implement safety strategies aimed at reducing risk for incidents of any kind.,,es,In a process of securitization of an industrial environment to be treated in one of the top network infrastructure, emerging concepts of separation and segregation.,,es,Separation,,es,Separation is the,,es,subnetting traditional IT environments and automation networks OT,,es,These must be installed element,,es,Network cybersecurity,,es,capable of filtering communications between the two environments.

When securing an industrial environment, one of the first areas to be addressed is the network infrastructure, which introduces the concepts of separation and segregation.

Separación

La separación es la separation of networks in traditional IT environments and OT automation networks.

A [element] must be installed between them network cybersecurity capable of filtering communications between the two environments. The most common option—although there are others—is NGFW which also adds an extra layer of security.,,es,Segmentation,,es,segmentation,,es,is the fractionalization of the environment OT either in cells, areas or small network or set of networks areas, so that in case of incident see only affected one without spread to others, thus avoiding putting in risk facilities.,,es,The golden rule is to ensure the highest availability, therefore, segmentation is essential as a method of prevention. Traffic must pass each small area, once again, by a,,es,and be influenced by pre-established security policy.,,es,Grassmarlin,,en,To carry out this process first thing you should do is,,es

Segmentación

The segmentación It involves dividing the OT environment—whether into cells, areas, or small zones within the network or set of networks—so that, in the event of an incident, only one of them is affected, without the incident spreading to the others, thereby preventing the facilities from being put at risk.

The golden rule is to ensure maximum availability; therefore, segmentation is essential as a preventive measure. Traffic from each small area must, once again, pass through a NGFW and be constrained by the preestablished security policy.

Grassmarlin

To carry out this process, the first thing you need to do is identify network traffic IC,,es,. One of the easiest and most efficient ways to achieve this is with,,es,Which identifies traffic, discover devices, makes logical and physical representations, graphics and architecture, export format information, etc.,,es,This is achieved passively, without interrupting operations teams. This is achieved either by interpreting the information contained in a PCAP either capturing traffic with the application itself.,,es. One of the simplest and most efficient ways to do this is with Grassmarlin, which identifies traffic, discovers devices, creates logical and physical representations, diagrams, and architectures, exports information to various formats, etc.

This is achieved passively, without interrupting the devices' operations. It is accomplished either by analyzing the information contained in a PCAP or by capturing the traffic using the application itself.

Configure a port-mirroring mode port so that we receive them back all traffic. Ways to do so will depend on the application you're using for it. In any case it is to get this information, formatting and exploit it according to your purpose.,,es,Grassmarlin to create and edit protocols and identifiers.,,es,If you do not use this application it is important to seek one that also permits.,,es,Applications of this type are extremely useful because they allow traffic identification IC networks easily and modification and customization options.,,es

Grassmarlin allows you to create and edit protocols and identifiers. If we don't use this app, it's important that we find one that offers the same functionality.

Applications of this type are extremely useful because they make it very easy to identify traffic on IC networks and offer options for modification and customization.
